Sergio Aguero rapped his Atletico Madrid teammates after yesterday's 1-1 draw with Almeria.
The Argentine striker said: "I am very angry. We have to react and start to train better so things change.
"We have to improve, last year we did just that. We had confidence and knew we could beat anyone. We have to get that mentality back.
"We were on a losing streak and it was important not to lose, but it was more important to win."
